SPECIFICATION forming part of Letters Patent No. 775,392, dated November22, 1904.

Application filed January 29, 1902. Serial No. 91,785. (No model.)

T0 all whom, it mfty concern,.-

Be it known that I, RUDOLPH OONRADER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania,haveinvented certain new and useful Improvements in Regulators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to regulators; and it consists in certainimprovements in the construction thereof. as will be hereinafter fullydescribed, and pointed out in the claims.

The invention is illustrated in the accompanying drawings, as follows:

Figure l shows a plan view, partly. in seetion, on the line l l in Fig.2. Fig. 2 shows a section on the line 2 2 in Fig. 1. Fig. 3 shows an endelevation from the right of Figs. l and 2. Fig. 4f is a partial sectionon the line 4 fl in Figs. l and 2.

A marks the valve-chamber; B, the valve; the valve-stem; C, the coverfor the valvechamber, from which project the extension O' and frame O2.The block b/ is secured to the stem The lever G is pivoted on thisblock. The lever G is provided with a guide g2, in which is fitted thefulcrurn-block g3. The fulcrum-pins g are secured to the block (f3 andextend into a sliding yoke gh The sliding yoke g* is secured in theguide c. A yoke c extends from the frame C2, and an adjustingscrew c2 isarranged in this yoke and operates upon the sliding yoke g4, so as tovary the position of the block g3 on the lever G, and consequently thearm of the lever, so that the stem and valve B are given a greater orsmaller' movement relatively to the movement of the outer end of thelever G. The outer endof the lever G is pivoted at g in a yoke IQExtending from the lower end of the yoke I is the stem 3. This stemrests upon the piston R. The piston R operates in the cylinder L. Thecylinder L is provided with the shoulder Z2 and is placed in an openingin the extension C@ A cap L is screwed onto the end of the cylinder, andthis, with the shoulder Z2, locks the cylinder in the extension C. Airor fluid under pressure is admitted to the cylinder L from the chamberM. It enters a chamber 7u* in the piston, passes through a minuteopening f to the bottom of the cylinder, and, exerting pressure here onthe bottom of the piston, the piston is made to rise and operate theregulating-valve B. Oil is preferably placed in the chamber z'", and theopening 1 forms a dash-pot, the opening being small enough for thispurpose. A minute opening' r opens into the passage J, and a lateralopening extends from the passage t' to the surface of the piston, thuslubricating the piston.

Arranged at the side of the yoke I are the arms I3. The springs I*connect these arms with the lu'gs L", extending' from the cylinder L.These springs form a counter-pressure device for the motor formed by thepiston K.

A supply-opening f/n/ leads from the cylinder N into the chamber IWI,anda minute vent m leads from the chamber M to the atmosphere. Arrangedin the opening m is the valve P, with the needle end p. The valve isprovided with a cap p at its end and is secured to a plunger O by meansof a Hangenut o, arranged in a cavity o in the plunger O. The plunger Ooperates in the cylinder N. The receiver-that is, any receptacle inwhich the Huid-pressure is regulated--connection N' leads into thecylinder N between the end of the plunger and the supply-opening m.Extending outwardly from the plunger is a stem O, which engages thelever Q. The mechanism for securing the spring to the lever comprisesthe adjusting-bolt r and thumbscrews lr', by which the bolt may belocked in position. Extending' from the lever Q is an arm Q', on whichis adjustably mounted the weight Q2. A screw q is provided for lockingthe weight in any position. An arm q extends from the upper end of thelever Q. A set-screw Q is arranged in this arm in position to limit theswinging of the lever Q and the outward movement of the plunger O. Ajam-nut q2 is provided for locking the set-screw in an adjustedposition.

The operation of the device is as follows: Air being admitted to thecylinder N above atmospheric pressure exerts pressure on the plunger O.The weight Q2 and the initial strength of the spring R are suficient tohold the valve P seated until themaximum desired pressure of thereceiver is reached; When the pressure in the receiver rises above thispoint, the plunger O is forced outwardly, thus moving the valve P fromits seat; but the needle-point remains in the supply-opening' m. Thespring R is relatively quite short, so that its strength or tensionincreases as the plunger moves. Thus the plunger'O will occupy a givenposition with a given receiver-pressure, and a given capacity of openingby the needle-point o is effected. The air passing into the chamber Mcreates pressure in said chamber. There is a constant escape of air orfluid from the chamber M through the vent m. The pressure in the chamberM, therefore, where the capacity of the supply-opening m is less thanthe size of the vent is not very materially increased; but where thesupplyopening is 'made considerably larger through the action of theplunger and the needle-valve then the pressure rises in the chamber M,and consequently in the cylinder L, in proportion to the difference inthe relative capacities of the openings m and m. The

springs IAi increasing in strength produce a given pressure with a givenpositionof the piston 1n the cylinder L, so that with a given -pressurein the cylinderL the piston K will occupy a certain position in saidcylinder,

thus giving to the yoke I a certain position,

and this acting through the lever G will control the valve B. The extentof movement of the valve B with a given movement of the piston K may beregulated by moving the fulcrum-blocls g3, or the amount of movement ofthe piston K may be regulated by varying the tension (any conve'nientmeans not shown may be used) or length of the springs If. The variationin pressure in the chamber M may be varied by varying the point p of theneedle-valve. This may be made more abrupt or more gradual in its taper.Again, this variation in pressure in the chamber M relative to thechange of pressure in the receiver may be controlled by adjusting thespring R. Where the'desired receiver-pressure is, for example, onehundred pounds and it is desired to keep this within one or two poundsof this pressure, it will be observed that the difference in pressure ifdirectly applied to the piston K would not so overcome the frictionalresistances of the parts as to effect a ready response of the piston. Byusing a secondary motor, as exemplified by the plunger O, with thesupply and vent openings and varying the relative capacities of thesethe pressure operating upon the piston-K can be made to vary almost anyper cent. desired, with a variation of two or three per cent. in thereceiver, so that a positive yet sensitive movement of the a movementofthe plunger O, while the spring R does this. The adjustment of theweight, therefore, is preferably used to change the moment at which thevalve P is open-that is, the receiver-pressure which will bring thregulating ldevice into operation.

It will be noted that with the present structure a givenreceiver-pressure within the limits of pressure desired will maintainthe piston K at a practically fixed. point so long as thereceiverpressure 'remains constant. The consequent adjustment of thevalve B is such as to give a constant supply to the receiver, so that ifthe outgofrom the receiver remains constant the parts will remain 'inone position.
